Overview

Pierson syndrome is a very rare condition that mainly affects the kidneys and eyes. Signs and symptoms include congenital nephrotic syndrome and distinct ocular (eye) abnormalities, including microcoria (small pupils that are not responsive to light). Most affected children have early-onset, chronic renal failure; neurodevelopmental problems; and blindness.[1] Hypotonia (poor muscle tone) and movement disorders have also been reported.[2] Pierson syndrome is caused by changes (mutations) in the LAMB2 gene and is inherited in an autosomal recessive manner.[1][2] The long-term outlook is poor; affected infants may not survive past the first weeks or months of life.[2][3]
